KV3.4 is a member of the voltage-gated K+ channel superfamily. Together with the related proteins KV3.1, KV3.2 and KVv3.3 they constitute the Shaw type subfamily family.As with all Kv channels, KV3.4 possesses the signature structure of the voltage-dependent K+ channels: six membrane-spanning domains with intracellular N and C termini. The functional KV channel is a tetramer that can either be a homomer or a heteromer of KV3 subunits
